도 1 내지 도 3에는 차량 서스펜션(40) 보조발전 시스템의 제1 실시예가 도시되어 있다. 1 to 3 show a first embodiment of the vehicle suspension 40 auxiliary power system.

도면을 참조하면, 차량의 서스펜션(40)은 휠과 타이어로 이루어지는 바퀴(10)의 휠에 결합되는 차륜지지부재(41)와, 이 차륜지지부재(41)를 차체에 연결하는 쇽업소버(42)와 서스펜션암(44)으로 이루어진다.Referring to the drawings, the suspension 40 of a vehicle includes a wheel support member 41 coupled to a wheel of a wheel 10 consisting of wheels and tires, and a shock absorber 42 connecting the wheel support member 41 to a vehicle body. ) And the suspension arm 44.

쇽업소버(42)는 차량이 평탄하지 않은 노면을 주행하는 경우 차체에 전달되는 진동을 감쇄시킬 수 있도록 설치되는데, 일단이 상기 차륜지지부재(41)에 고정되고 타단은 차체프레임(20)에 지지되어 있으며, 스프링(43)이 포함되어 있다. 이와 같은 쇽업소버(42)의 구조는 일반적인 차량의 현가장치에 적용되는 쇽업소버(42)의 구성과 동일하므로 상세한 설명은 생략한다.The shock absorber 42 is installed to attenuate the vibration transmitted to the vehicle body when the vehicle travels on an uneven road surface, one end of which is fixed to the wheel support member 41 and the other end of which is supported by the body frame 20. And a spring 43 is included. Since the structure of the shock absorber 42 is the same as that of the shock absorber 42 applied to the suspension device of a general vehicle, detailed description thereof will be omitted.

아울러 상기 차륜지지부재(41)에는 변속기(30)로부터 연장되어 변속기(30)의 동력을 차륜에 전달하는 등속축(31)이 연결되어 있으며, 쇽업소버(42)와 대향되는 위치에는 서스펜션암(44)이 볼조인트(45)를 통해 연결되어 있다.In addition, the wheel support member 41 is connected to a constant speed shaft 31 extending from the transmission 30 to transmit the power of the transmission 30 to the wheels, and the suspension arm at a position opposite to the shock absorber 42. 44 is connected via a ball joint 45.

본 실시예의 경우 후륜구동 차량의 후방서스펜션(40)이기 때문에 차륜지지부재(41)에 등속축(31)이 결합되어 있으나, 전륜구동 차량인 경우 또는 전방 서스펜션(40)인 경우 상기 등속축(31)이 생략될 수도 있고, 차륜의 조향을 위한 조향링크가 차륜지지부재(41)에 추가로 연결될 수도 있다.In the present exemplary embodiment, since the rear suspension 40 of the rear wheel drive vehicle is coupled to the wheel support member 41, the constant speed shaft 31 is coupled to the wheel support member 41. In the case of the front wheel drive vehicle or the front suspension 40, the constant speed shaft 31 is used. ) May be omitted, and a steering link for steering of the wheel may be further connected to the wheel support member 41.

상시 서스펜션암(44)은 상술한 것처럼 일단이 차륜지지부재(41)에 볼조인트(45)를 통해 연결되어 있으며, 타단은 차체프레임(20)에 회전 가능하게 결합되어 있다.The suspension arm 44 is one end is connected to the wheel support member 41 through the ball joint 45 as described above, the other end is rotatably coupled to the body frame 20.

차체프레임(20)에는 상기 서스펜션암(44)이 회전 가능하게 지지될 수 있도록 결합핀(21)이 돌출되어 있고, 상기 서스펜션암(44)의 타단부에는 상기 결합핀(21)이 끼워지는 중공을 갖는 베어링(46)이 마련되어 있어서, 서스펜션암(44)이 결합핀(21)이 끼워진 타단부를 중심으로 상하로 회전이 가능하게 된다. 따라서 차량이 주행하는 동안 노면이 고르지 않아 진동이 발생하더라도 차륜과 차체가 안전하게 연결상태를 유지할 수 있다.A coupling pin 21 protrudes from the body frame 20 so that the suspension arm 44 can be rotatably supported, and a hollow in which the coupling pin 21 is fitted at the other end of the suspension arm 44. The bearing 46 is provided so that the suspension arm 44 can be rotated up and down about the other end on which the coupling pin 21 is fitted. Therefore, even if the road surface is uneven during driving, even if the vibration occurs, the wheel and the body can be safely connected.

이 서스펜션암(44)에는 회동부재(50)가 연장형성되어 있다.The suspension member 44 is extended with the rotation member 50.

회동부재(50)는 서스펜션암(44)의 일측으로부터 하방으로 연장되는 제1 연장부(51)와, 제1 연장부(51)의 단부에서 차체측으로 절곡되어 연장된 제2 연장부(52)와, 제2 연장부(52)의 단부 상면에 부착된 탄력커버(53)로 이루어져 있다.The rotation member 50 includes a first extension part 51 extending downward from one side of the suspension arm 44 and a second extension part bent and extended from the end of the first extension part 51 toward the vehicle body side. And an elastic cover 53 attached to the upper end surface of the second extension portion 52.

회동부재(50)는 후술하는 압전소자(60)를 가압하기 위한 것인데, 차량의 진동에 의해 서스펜션암(44)이 상기 결합핀(21)을 중심으로 회동이 이루어질 때, 회동부재(50)의 단부가 차체프레임(20)을 향하는 방향으로 회전하면서 압전소자(60)를 접촉 또는 가압이 이루어지도록 형성되어 있다. 상기 회동부재(50)의 형상은 본 실시예에 한정되지 않고, 회동부재(50)가 차량의 진동에 의해 회전하는 과정에서 압전소자(60)를 가압할 수 있으며 차체프레임(20)의 다른 부분 또는 차량의 다른 구성요소들과 간섭이 발생하지 않을 수 있는 다양한 형태로 이루어질 수 있다.The rotating member 50 is for pressing the piezoelectric element 60 to be described later.

특히 탄력커버(53)는 압전소자(60)와 직접 접촉하는 부분에 형성되는데, 탄성력이 있는 고무재 또는 합성수지재로 형성되어서 서스펜션암(44)의 회전이 지나치게 커, 압전소자(60)를 과압하는 경우 탄력커버(53)가 변형되면서 압전소자(60)의 과압을 방지한다.In particular, the elastic cover 53 is formed in a portion in direct contact with the piezoelectric element 60, is formed of a rubber material or a synthetic resin material with elasticity is too large rotation of the suspension arm 44, over-pressure the piezoelectric element 60 When the elastic cover 53 is deformed to prevent overpressure of the piezoelectric element 60.

압전소자(60)는 상술한 것처럼 차체프레임(20)의 하면에 부착되며, 차량의 진동에 의해 서스펜션암(44)이 회전하면 상기 회동부재(50)의 단부가 압전소자(60)를 가압해 전기를 발생시킨다. 도시되지는 않았으나 상기 압전소자(60)에서 발생한 전기는 차량의 배터리(80)를 축전하는데 이용되거나, 차량의 구동을 위한 구동부에 직접 전달될 수도 있다.The piezoelectric element 60 is attached to the lower surface of the body frame 20 as described above, and when the suspension arm 44 rotates due to the vibration of the vehicle, the end of the rotating member 50 presses the piezoelectric element 60. Generate electricity. Although not shown, electricity generated from the piezoelectric element 60 may be used to accumulate the battery 80 of the vehicle, or may be directly transmitted to a driving unit for driving the vehicle.

Energy efficiency can be improved by converting kinetic energy into electrical energy and reusing it.

본 실시예에서는 서스펜션암(44)의 회동에 따른 운동에너지를 전기에너지로 변환시키는 발전유닛으로 압전소자(60)가 적용되었으나 발전유닛은 이 외에도 다른 형태로 형성될 수도 있다.In this embodiment, the piezoelectric element 60 is applied as a power generation unit for converting kinetic energy into electric energy due to rotation of the suspension arm 44, but the power generation unit may be formed in other forms.
